print name of first key in a array

[marc01]

Hi,

The following script doesnt print the names of the categories category1, category2 and category3.

Can anybody give me an idea how to print the names category1, category2 and category3? I just get a number printed with this scripts.

ciao,

Marc

<?php

$categories = array(

array('Category1' => array('Name1', 'Price1', 'Link1'),
array('Name2', 'Price2', 'Link2'),
array('Name3', 'Price3', 'Link3')),

array('Category2' => array('Name4', 'Price4', 'Link4'),
array('Name5', 'Price5', 'Link5'),
array('Name6', 'Price6', 'Link6')),

array('Category3' => array('Name7', 'Price7', 'Link7'),
array('Name8', 'Price8', 'Link8'),
array('Name9', 'Price9', 'Link9'))

);

echo "<ul>\n";
foreach( $categories as $category => $changes )
{
echo ' <li><b>'.$category."</b>.<br />\n";
echo " <em>Changes</em>: </li>\n";
echo " <ul>\n";
foreach( $changes as $change )
{
echo ' <li>'.$change[0] .$change[1] .$change[2].".</li>\n";
}
echo " </ul>\n";
}

echo "</ul>\n";
